This document discusses project-based learning (PBL) and provides examples. It defines PBL as involving complex tasks based on challenging questions that require students to engage in design, problem-solving, decision making or investigations over an extended period of time, culminating in a tangible product or presentation. Key aspects of PBL include being centered around core concepts, driven by questions, involving constructive investigations, giving students autonomy, and addressing real-world problems. Examples provided include students designing an "amazing race" learning experience and investigating climate science through data collection.
